Definitions
- the present application relates to a polymeric colorant, ink compositions comprising a polymeric colorant and a method of forming a polymeric colorant.
- Colorants are widely used in many applications to provide useful and aesthetic appearance to articles and printed images. Standard colorants can most often be classified as either pigments or dyes. Although such colorants can be directly mixed into an article of manufacture, it is often desirable to prepare ink compositions containing colorants for printing of color images.
- Such ink compositions typically include a liquid vehicle such as an appropriate solvent containing the dye or the pigment.
- Dye-based inks generally use a colorant that is soluble in the given liquid vehicle.
- pigmented inks typically use an insoluble dispersed solid colorant to achieve color.
- Dye and pigment colorants each have certain properties which are beneficial in certain circumstances and can provide predetermined color properties to a printed image.
- dye colorants also have various limitations and drawbacks which present unique challenges. Specifically, dye colorants exhibit good chroma and long-term stability in solution. However, dye colorants also tend to have poor waterfastness, lightfastness, and smear resistance. In contrast, pigment colorants typically have good waterfastness, good lightfastness, and good smear resistance. Unfortunately, pigment colorants also tend to have limited chroma and a myriad of issues related to maintaining the pigment particles dispersed in solution. Thus, pigment particles of pigment inks can often settle over time.
- a polymeric colorant includes a pigment having a polymer covalently attached thereto, a dye covalently attached to the polymer, and a dispersant covalently attached to at least one of the pigment, the polymer, and the dye, wherein the dye covalently attached to the polymer includes a reactant coupled to the dye and to the polymer.
- an inkjet composition includes a polymeric colorant with a pigment having a polymer covalently attached thereto, a dye covalently attached to the polymer, and a dispersant covalently attached to at least one of the pigment, the polymer, and the dye, wherein the dye covalently attached to the polymer includes a reactant coupled to the dye and to the polymer.
- the composition preferably includes a liquid vehicle wherein the polymeric colorant is dispersed therein.
- an inkjet composition includes a liquid vehicle having a polymeric colorant dispersed therein, said polymeric colorant including: a pigment; a polymer covalently coupled to said pigment; a dye covalently attached to said polymer, and a dispersant covalently attached to at least one of said pigment, said polymer, or said dye; wherein said dye is esterified with said polymer, said polymer having a carboxyl group.
- the polymer may comprise a styrene acrylic acid copolymer.
- Preferably the polymer comprises a Joncryl® polymer.
- an inkjet composition comprises a liquid vehicle; a pigment having a polymer covalently attached thereto; a dye covalently attached to the polymer; and a dispersant covalently attached to at least one of the pigment, the polymer, and the dye; wherein said dye is attached to said polymer via a one step modification of a dye derivative.
- the dye derivative may be derivatized with said polymer.
- the dye derivative comprises xanthylium, 9-[4-(Chlorosulfonyl)-2-sulfophenyl]-3,6-bis (diethylamino)-, inner salt (9Cl).
- the one step modification of said dye derivative may comprise coupling said dye derivative to said polymer with an adduct.
- said adduct comprises an ethylenediamine adduct.
- the polymer may be copolymerized with a vinyl containing monomer.
- said vinyl containing monomer comprises one of a styrene, an acrylic acid, a methacrylic acid, a benzyl acrylate, or a butyle acrylate.
- the vinyl containing monomer may comprise one of the following structures: Wherein R is either hydrogen or a methyl group.
- a method of forming a polymeric colorant comprising: attaching a dye to a polymer to form a polymer-dye colorant; attaching the polymer to a pigment; and attaching a dispersant to at least one of the polymer-dye colorant and the pigment; wherein said attaching a dye to a polymer includes covalently attaching a reactant to said dye and to said polymer.
- liquid vehicle is defined to include liquid compositions that can be used to carry colorants, including pigments, to a substrate.
- Liquid vehicles are well known in the art, and a wide variety of liquid vehicle components may be used in accordance with embodiments of the present exemplary system and method.
- Such liquid vehicles may include a mixture of a variety of different agents, including without limitation, surfactants, solvents, co-solvents, buffers, biocides, viscosity modifiers, sequestering agents, stabilizing agents, and water.
- the liquid vehicle can also carry other solids, such as polymers, UV curable materials, plasticizers, cosolvents, salts, etc.
- pigment refers to a colorant particle which is substantially insoluble in the liquid vehicle in which it is used.
- die refers to a colorant compound which is substantially soluble in the liquid vehicle in which it is used.
- pigment particles which have a compound chemically attached via covalent bonds. This is in contrast to pigment particles which have compounds attached via ionic bonds or other weaker intermolecular forces.
- bleed refers to the tendency of ink to run into and mix with adjacently printed inks. Bleed typically occurs prior to adjacently printed inks fully drying on a substrate. The degree of bleed will depend on a variety of factors such as the drying speed of the ink, ink chemistry, i.e. the presence of reactive or non-reactive bleed control mechanisms, and type of substrate, among other variables.
- waterfastness refers to an ink's exhibited degree of water resistance after printing on a substrate. Typically, this property is measured after the ink has dried, and measures the tendency of the ink to smear or otherwise change location in the presence of moisture.
- chroma refers to the attribute of color used to indicate the degree of departure of the color from gray of the same lightness as defined by ASTM (ASTM E 284). It is also used to refer to degree of saturation of color which is the ratio of chroma over lightness (C*/L*). Typically, dye colorants have a greater degree of saturation over pigment colorants having the same, or substantially the same, hue.
- neutral gray refers to a shade of gray which exhibits a substantial color constancy, i.e. substantially no change in color appearance when viewed under different light sources such as fluorescent and sunlight. Further, non-neutral gray colors also tend to have a subtle red or brown shade or appearance.
- reactive when referring to ink sets refers to a chemical reaction between two or more ink-jet inks. Such reactive ink sets can interact either by salt mechanisms, pH differential mechanisms, polymerization mechanisms, or other reactive mechanisms known to those skilled in the art.

- the dispersing agent can be a small molecule or a polymer.
- polymer-dispersed pigment refers to a type of self-dispersed pigment wherein the pigment is attached to or is at least partially encapsulated by a polymer.
- the polymer can be covalently attached to the pigment surface, either directly or via an intermediate attachment group, or can be attached through non-covalent intermolecular attractive forces.
- a colorant which has a color "substantially” that of another colorant may deviate in color, i.e. hue, or other relevant property within a range which is imperceptible or nearly imperceptible upon visual inspection.
- hue i.e. hue
- other properties can vary considerably.
- a black pigment can have substantially the same color and hue as a black dye; however, chroma, optical density, gloss, solubility, and the like can differ dramatically from one another.
- identification of a property which is "substantially different” indicates a visible and/or measurable degree of difference.
- a weight range of approximately 1 wt% to about 20 wt% should be interpreted to include not only the explicitly recited concentration limits of 1 wt% to about 20 wt%, but also to include individual concentrations such as 2 wt%, 3 wt%, 4 wt%, and sub-ranges such as 5 wt% to 15 wt%, 10 wt% to 20 wt%, etc.
- a polymeric colorant can include a pigment having a polymer covalently attached thereto.
- a dye can be covalently attached to the polymer through esterification or by derivitizing the dye with a polymerizable group.
- a dispersant can be covalently attached to at least one of the pigment, the polymer, and/or the dye to provide dispersion stability to the polymeric colorant in a liquid vehicle.
- the polymeric colorant can benefit from the properties of each.
- the dye and pigment components can be substantially the same color, or can be of different colors, depending on the desired appearance.
